Abstract

The method of providing location-based information from portable devices allows for the tracking of the location of portable devices (14), such as cellular telephones, for example, for the recordation and subsequent analysis of demographic, location-based information. The method includes the steps of: determining (200) a geographic location of at least one portable device (14); recording geographic location coordinates (250) of the portable device (14) in computer readable memory (140); establishing a set of public geographic regions (20) and a set of non-public geographic regions (30) within a geographic area in which the portable device (14) is located; and dividing each non-public geographic region (30) into a plurality of geographic non-public zones (52), where if the portable device (14) is located within a non-public geographic region (30), the geographic location coordinates are replaced (260) with a generalized set of geographic coordinates associated with the non-public geographical region (30).

Claims

1. A method of providing location-based information from anonymous portable devices, comprising the steps of:

determining a geographic location of at least one anonymous portable device;

recording geographic location coordinates of the at least one anonymous portable device in computer readable memory; and

establishing and maintaining a set of preexisting, community recognized public geographic regions and a set of preexisting, community recognized non-public geographic regions within a geographic area in which the at least one anonymous portable device is located, wherein if the at least one anonymous portable device is located within the preexisting, community recognized non-public geographic region, the geographic location coordinates associated with the at least one anonymous are automatically replaced with a generalized set of geographic coordinates associated with the preexisting, community recognized non-public geographical region, and if the at least one anonymous portable device is located with the preexisting, community recognized public geographic region, the geographic location coordinates associated with the at least one anonymous portable device remain unchanged.

2. The method of providing location-based information from portable devices as recited in claim 1, further comprising the step of dividing each non-public geographic region into a plurality of geographic non-public zones.

3. The method of providing location-based information from portable devices as recited in claim 2, wherein the replacement of the geographic location coordinates associated with the at least one portable device with the generalized set of geographic coordinates associated with the non-public geographical region includes replacing the geographic location coordinates associated with the at least one portable device with location coordinates of the geographic non-public zone in which the at least one portable device is located.

4. The method of providing location-based information from portable devices as recited in claim 3, wherein the replacement of the geographic location coordinates associated with the at least one portable device with the generalized set of geographic coordinates associated with the non-public geographical region further includes replacing the geographic location coordinates associated with the at least one portable device with location coordinates of a centroid of the geographic non-public zone in which the at least one portable device is located.

5. The method of providing location-based information from portable devices as recited in claim 3, further comprising the step of establishing at least one density map for the geographic area, wherein the replacement of the geographic location coordinates associated with the at least one portable device with the generalized set of geographic coordinates associated with the non-public geographical region further includes replacing the geographic location coordinates associated with the at least one portable device with location coordinates based upon population density within geographic non-public zone.

6. The method of providing location-based information from portable devices as recited in claim 1, further comprising the step of recording time-based data associated with each set of geographic location coordinates which are recorded in the computer readable memory.

7. The method of providing location-based information from portable devices as recited in claim 6, further comprising the step of establishing a user-selectable time interval for determining the geographic location coordinates of the at least one portable device, and recording a set of geographic location coordinates and time-based data for each time interval.

8. The method of providing location-based information from portable devices as recited in claim 7, further comprising the step of plotting at least one set of geographic location coordinates on a graphical representation of the geographic area.

9. The method of providing location-based information from portable devices as recited in claim 8, further comprising the step of plotting a time-based geographic path of the at least one portable device on the graphical representation of the geographic area.

10. The method of providing location-based information from portable devices as recited in claim 1, further comprising the step of establishing a user-selectable level of non-public associated with the at least one portable device.

11. A method of providing location-based information from portable devices, comprising the steps of:

determining a geographic location of at least one portable device;

recording geographic location coordinates of the at least one portable device in computer readable memory;

establishing a set of public geographic regions and a set of non-public geographic regions within a geographic area in which the at least one portable device is located;

dividing each non-public geographic region into a plurality of geographic non-public zones, wherein if the at least one portable device is located within a non-public geographic region, the geographic location coordinates associated with the at least one portable device are replaced with a generalized set of geographic coordinates associated with the non-public geographical region, and if the at least one portable device is located within a public geographic region, the geographic location coordinates associated with the at least one portable device remain unchanged, the replacement of the geographic location coordinates associated with the at least one portable device with the generalized set of geographic coordinates associated with the non-public geographical region includes replacing the geographic location coordinates associated with the at least one portable device with location coordinates of the geographic non-public zone in which the at least one portable device is located, wherein the location coordinates comprise a centroid of the geographic non-public zone in which the at least one portable device is located;

recording time-based data associated with each set of geographic location coordinates which are recorded in the computer readable memory; and

establishing a user-selectable time interval for determining the geographic location coordinates of the at least one portable device, and recording a set of geographic location coordinates and time-based data for each time interval.

12. The method of providing location-based information from portable devices as recited in claim 11, further comprising the step of plotting at least one set of geographic location coordinates on a graphical representation of the geographic area.

13. The method of providing location-based information from portable devices as recited in claim 12, further comprising the step of plotting a time-based geographic path of the at least one portable device on the graphical representation of the geographic area.

14. The method of providing location-based information from portable devices as recited in claim 13, further comprising the step of establishing a user-selectable level of privacy associated with the at least one portable device.

15. The method of providing location-based information from portable devices as recited in claim 14, further comprising the step of selectively replacing the geographic location coordinates associated with the at least one portable device with a generalized set of anonymous geographic coordinates.

16. The method of providing location-based information from portable devices as recited in claim 15, further comprising the step of recording a plurality of virtual geographic maps associated with the geographic area within the computer readable memory.

17. The method of providing location-based information from portable devices as recited in claim 16, further comprising the step of sampling the geographic location of the at least one portable device over a predetermined time interval, said predetermined time interval being selected as a portion of day.
